Him backed around me in one part so comical? (9,5)
I believe the answer is:
pantomime horse
'part so comical?' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'him backed around me in one' is the wordplay.
I cannot really see how this works, but
'him' could be 'tom' and 'tom' is found within the answer.
'around' could be 'o' (I've seen this in other clues) and 'o' is found within the answer.
'me' could be 'i' and 'i' is located in the answer.
'one' could be 'an' (I've seen this in other clues) and 'an' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for pantomime horse that I've seen before include "Christmas double act" , "Christmas show character" , "Costume for two performers" .)
